Yes, home brewed beer (and any beer period) is better and should be served in a nice clean glass with a nice head accompanying it.
I fully acknowledge this.

But still, I have to ask how it is to drink straight out of the bottle rather than pouring it into a glass/cup.
The reason I ask is my friends and I are planning to take a camping trip (somewhere), and I wanted to bring along some bottles of home brewed beer for the occasion.
Sure I can bring along plastic cups to at least make the situation a little bit better, but I'd rather avoid the hassle of extra luggage if I could.

My guess is the sedimentation on the bottom of the bottle will get disrupted and alter the taste of the beer (how much... I don't know, because I've never tried), but besides that is it "safe" in the sense that it won't cause any sickness?

Any info will be wonderful! Any tips on drinking home brewed beer at camping/trip destinations would be great too.
Thanks ahead!

No problem whatsoever. I often have big suppers/ brewparties and everyone drinks straight from the bottle. I slosh the last bit to get that yeast (it's probiotic woo woo) but most people drink them normally. I've never had any complaints about yeasty bottoms either.

If someone on the trip is allergic or somehow irritated by yeast you might have a little problem but otherwise don't worry about it.

It really depends on how cleared the beer was before it went into bottles. If you bottled too soon, theres going to be a ton of trub/yeast. If your beer is pretty clear before going in bottles, there won't be.

I think the best bet would be 2 liter PET pop bottles, not glass. I can't see breaking the bottle just before getting to drink it. I assume your backpack camping right, otherwise load the car to the "gun wales" with bottles and glasses.
